fix(guix): restore preference-injector identity in guix.scm (#58)

`guix.scm` declared `(name "squisher-corpus")` — the squisher clobber.
Measured across all 418 estate repos: **45 affected**.

Fixes **identity only** — name, synopsis, description, home-page, header
comment.

The `(license ...)` form is **deliberately untouched**; the licence
drift (58 repos asserting PMPL) is a separate owner decision. Verified
byte-identical (md5 of the licence form before and after).

Commit is GPG-signed — the earlier contents-API attempt produced
unsigned commits, which `required_signatures` rejected.
